The Excursion Graph in Detail
(Sealed Box)
This is the amount of RMS power applied
This is the distance the cone will move
This is the frequency scale
This graph shows how far the cone will
move at the frequencies the box will play
when a certain amount of power is applied
– In a sealed box, excursion is greatest at low
frequencies.
5
frequencies.
– This graph shows that in a sealed box, 125 W
RMS will ALMOST drive the woofer to Xmax. The
graph shows about 5.5mm of excursion at 125
WRMS
– It’s OK to apply a little more power than RMS
because it’s OK to exceed Xmax by about 20
percent.
– For a bass-enthusiast who will listen as loud as
possible, a 150 Watt amplifier is about the right
amount of power.
